KING- BOLT.

SPECIFICATION forming part of Letters Patent No. 262,451, dated August 8, 1882.

Application tiled December 23, 1881. (No model.)

To all whom it may concern Be it known that I, HUGH MCFARLANE, of Chicago, in the county ot' Cook and State of Illinois, vhave invented certain new and useful Improvements in King-Bolts; and I do hereby declare that the following is a full, clear, and exact description of theinvention, which will enable others skilled in the art to which it appertains to make and use the same, reference being had to the accompanying drawings, and to letters of reference marked thereon, which i'orm a part of this specification.

My invention relates to improvements inl kin g-bolts for wagons and similarfour-wheeled vehicles, the same enteringthe point of oscillation from beneath, and said king-bolt and king-bolt guard being made in one piece, in contradistinction to those which en terthe point ot' oscillation from above, and in which the king-bolt and king-bolt guard are made separate.

The object of my invention is to furnish a king-bolt for wagons and similar vehicles which will be less liable to Wear itself or the contiguous parts in and against which it may he used, which is stronger and less liable to get out of order or in need of repairs, and which avoids rattling.

In the drawings, Figure 1 is a side elevation ot' my king-bolt as applied to a wagon. Fig. 2 is an end view of the same, and Fig. 3 is a separate view of king-bolt and kin g-bolt guard.

In the drawings, A represents the axle and axle-bed, B the headblock, and C the reach in connection with which my invention may be used.

Fastened to the under side of the head-block, and running a suitable distance back on the reach C, is a T-shaped plate, a, the same being secured by bolts and nuts and forming the engagging-surface ot' the D-plate or fifth-wheel.

The fifth-wheel b is similar to the ordinary fifth-wheel common in wagons, Src., it being semicircular in shape and having its ends connected with a strip, which is secured to the axle-bed and lies immediately under that portion of the T-plate ca under the head-block.

Placed longitudinally on the under side of the plate a on the reach C, and secured thereto.

by bolts, is a guide, c, said guide being so located that it passes under and around the semicircular part of the fifth-wheel, preventing the same from vibrating.

Fastened to and projecting from that lug of the guide nearest the head-block-or, it' preferred, forming a part of the same-is a tlat curved spring, c', which, passing downward and under that part of the guide in which operates the fifth-wheel, runs longitudinally or in the same direction as the reach and presses downward on the curved continuation or kingboltguardof theking-bolt with sufficient pressure to prevent said kingbolt, 85o., from rattling, as will be hereinafter more fully described. f

D represents an eye fastened at a suitable Adistance from the axle on the under side ofthe reach, and extending downward to receive the ring or hook e on the end ot' the continuation of the king-bolt or king-bolt guard o', said continuation pursuing a curved course from said eye to the center of oscillation on the under side of the axle, where it merges into a head, e2. This head c2 is convex on its under side, as shown in the drawings, iittinginto and oscillatin g in a corresponding coucavity in the socket F, the arms g g on either side of which extend in the direction of length of and are bolted to the axle A, said socket and arms thereof forming a brace and rest for the pintle and head of the kingbolt. Projecting vertically and upward from said head e2 through the axle-bed and head-block to a level with the top ot' the reach, forming the center of oscillation7 is a pintle, G, said pintle G, head 62, and curved continuation c being made in one piece and forming a continuous king-bolt and guard, the same being' the principal feature of' my invention.

It will he readily seen that my invention, as hereinbefore described, is less liable to wear, rattle, or get out of order or in need of repairs than those now invuse, and being connected with the contiguous parts, it acquires their several motions, which, when contrary, are modified by the pressure of the ilat spring'.

What I claim as new, and desire to secure by Letters Patent, is-

1. A continuous king-bolt and guard, commencing from a position ou the reach hereinbefore speciiiethand pursuingalongitudinallycurved course to the pointof oscillation on the under side of the axle, where it merges into a head, from which extends upward a vertical pintle, all of which is made in one piece, substantially as and for the purpose set forth.

2. A king-bolt entering the point of oscillation from beneath, at which point it is provided with a head convex on its under side to enter and oscillate in a concave or socket bearing, said socket having arms ou either side extending in the length of the axle and secured to the under surface thereof by bolts or screws, as and for the purpose specified.

3. The combination, with a king-bolt having a continuation or guard extending from the point of oscillation on the under side of the axle to and secured at a given point on the reach, of a spring located above and pressing downward on said guard, as and for the purpose set forth.

HUGH MCFARLANE.
